' MANUFACTURE OF BOX-COVERS.

To all whom it may concern:

Be it known that I, HARRY Born, a citizen of the United States, and aresident of the city, county, and State of New York,

have invented certain new and useful Improvements in the Manufacture ofBox- Covers, of which the following is a specification.

My invention relates particularly to improvements in covers for boxes ofthe type commonly known as two-piece or three-piece cases which aregenerally made of paper-board or similar material and consist either oftwo cover sections fitting one into the other, or of a rectangular bodyshell capable of being knocked-down and provided, when set up, with acover fitting over each of its ends. Such cases are ordinarily used forshipping various articles of It has been found in practice, that owingto the rough handling to which the cases are subjected in transit, theflaps and corners of the covers thereof are often pulled out of shape,thereby weakeni ing or tearing said parts and diminishing or destroyingthe utility of the case.

One of the objects of my invention is to provide a cover having its sideflaps and corners strengthened by means of reinforcing bands which areapplied so as to effectually prevent tearing-out of the corners orbreaking of the flaps while allowing sufficient flexibility to permit ofthe boxes being readily assembled by fitting the covers over each otheror over an intermediate body shell as desired.

Another object of my invention is to secure the parts of the cornerjoints together by means of bands of a strong pliable material whichbands extend around the side flaps of the cover and are suitablyfastened thereto so as to form corners that are practically unbreakableand will hold their shape.

In the accompanying drawings illustrating my invention Figure 1 is aperspective view of a box cover constructed according to my inventionand having part of the trimming or ornamental covering broken away toshow the reinforcing bands. Fig. 2 is a vertical section on the line aaof Fig. 1. Fig. 3 is a detail longitudinal sectional-view through one ofthe staples fastening the band to the flap. Fig. 4: is a detailsectional view of a modification showing the band Specification ofLetters Patent. Patented Feb, 22, 1916 Application filed May 14, 1915. I

provided with an integral tang for attaching it to the flap. Fig. 5 is aplan view of the same, and, Fig. 6 is a perspective view of one cornerof a box cover showing a modification in which one of the reinforcingbands is bent in angular form to fit over the edge of the cover.

Referring to the drawings, 1 indicates the cover which is made of plainor corrugated paper-board or other suitable material and of any desiredshape or form.

In manufacturing the covers I employ blanks similar to those now used inconstructing box-covers of a like character and are well known to thoseskilled in the art of paper-board box making. Such blanks have integralears or extensions which are formed by cutting out the corner portionsof the blank and which constitute, when bent perpendicular to the planeof the body of the blank, the side walls or flaps 2 of the 7 cover.After the box-coverhas been bent into shape, I bind the side flaps 2together with bands or strips 3 of metal ribbon or other suitable strongand pliable material. The bands are passed snugly around the flaps,preferably on the outside, and are secured thereto by wire stitching orstaples a set therein at intervals along their length. One of the bandsis preferably located close to the bent edges of the cover, as shown inFig. l, to serve as a guard to prevent said edges from being crushed orcut when the box is tightly tied with cord.

Any suitable mechanism may be employedv for applying the bands andfastening them to the box, and such mechanism will preferably bearranged to apply all of the bands at one operation. If desired,however, the bands may be applied singly either by hand or otherwise,and the staples set therein with an ordinary stapling machine.

' The adjoining edges of the side walls or flaps 2 forming the corners 5of the cover are tied together solely. by means of the metal bands 3which pass around the flaps and are fastened thereto at several points,thereby increasing the strength of the flaps and producing a simple andstrong corner structure.

In the modifications shown in Figs. 4 and 5, the bands are perforated,by means of a suitable punch, to produce integral tangs 6 which serve tofasten the bands to the flaps.

If desired the top edges of the cover may be further reinforced, asshown in Fig. 6, by bending the upper band 7 in angular form to i'itsnugly over said edges.

The cover is trimmed in the usual manner with an ornamental covering oredging 8, made of craft paper, cloth or other suitable material, whichcovedng conceals the reinforcing bands and gives the structure a neatand finished appearance. The machine which is employed to apply andfasten the bands may also be arranged to apply the covering thereon.

Various modifications in the form and construction of the boxover hereinillustrated and described may be made without departing from the scopeof my invention, and I do not therefore limit myself to the precisestructure set forth except in so far as I am limited by the claims.

lVhat I claim is:

l. A paper-board boX cover having a plurality of narrow bands of pliablemetallic ribbon encompassing the side walls and corner joints thereof,each band being integral and continuous and being fastened to the wallswhereby to reinforce said walls and to stay the corners, and a trimmingsheet applied to the side walls and covering the metallic bandssubstantially as described.

2. A paper-board boX cover having a plurality of narrow bands of pliablemetallic ribbon encompassing the side walls and corner joints thereof,each band being integral and continuous and being secured to the wallsat intervals by means of integral fastening tangs, whereby to reinforcesaid walls and to stay the corners, and a trimming sheet applied to theside walls and covering the metallic bands substantially as described.

3. A box cover comprising a paper blank bent to form the top and sidewalls of the cover, a plurality of metallic reinforcing bandsencompassing the side walls and corner joints, each of said bands beingintegral and continuous and being fastened to the said bands being topedge of the and continuous and being fastened to the walls at intervals,one of said bands being disposed along and overlapping the top edge ofthe cover.

In testimony whereof, I have hereunto affixed my signature in thepresence of two subscribing witnesses.
